I'm heading home from work in about 20 minutes, and I was thinking of starting up some X-2 action. I was looking around this subforum for info, and ran across the term Oversoul. Anyone tell me what is it/how to do it/if it's useful? I couldn't really tell anything about it.

Two things I managed to learn about it:
-You can steal rare items easier with oversoul?
- An item that does 99,999 each hit will diminish if you run away ( it mentioned oversouling too)

Any other help about the game is appreciated.

Basically, if you defeat a certain number of a monster, that monster will gain the ability to go into Oversoul. I can't help you with the 99,999 per hit item, but Oversoul enemies are generally stronger, and carry rarer or better loot.

^Thanks for the help, the game also did a surprisingly good job of explaining it as well.

And I think the item I was talking about was 'the Finale'? or 'the End'? Not too important though.

If you oversoul ever enemy you get "The End" garment grid which has Finale on it, and yes it does 99999 damage which reduces every time you run away. However, by far the quickest way to get all the oversouls is by escaping, as if you escape from an oversouled monster then the next one you encounter of the same species will oversoul (and this carries on until you kill the oversoul!) - if you wanted to use Finale it'd be much better in a new game +.

Yeah, Melti pretty much covered "The End". Also, monsters in Oversoul have a bunch of changes in their stats. More HP, different steal/drop items, different set of attacks, different scan description, and more. Think of it as them being on steroids.

Sometimes these changes can be for the better of for the worse. Like, some bosses (those can be oversouled too) are far easier to beat in Oversoul mode. Also, about different attack patterns, some of the Gun Mage's Blue Bullet (this game's Blue Magic) can be learned from very very specific enemies only when in Oversoul mode, and some from monsters only in non-Oversoul mode.
